Nearly two in five (38%) supported Dean, giving him a substantial lead over Massachusetts Senator John Kerry at 17%. In February polling in New Hampshire, Kerry led Dean, 26% - 13%. In June, the gap had narrowed to Kerry 25%, Dean 22%.

All other Democratic presidential hopefuls remained in single digits, with Connecticut Senator Joseph Lieberman and Missouri Congressman Richard Gephardt tied at 6%, followed by North Carolina Senator John Edwards at 4%, and Florida Senator Bob Graham and Ohio Congressman Dennis Kucinich at 1% each. Former NATO Commander and retired General Wesley Clark, not yet a declared candidate, earned 2%.

Dean's increase of 16% over the amount he recieved in Zogby's last poll comes half from Kerry, a quarter from the other candidates, and a quarter from those undecided voters. There still remain 23% who are unsure of who they will support, but it's clear that Dean is the frontrunner.
